Michael - do you know what metal the hull is made from - steel, aluminium, brass etc. - this should point you in the direction of a repair scheme...?

I would start looking at the more obvious areas eg prop shaft outlets, rudder posts etc. for leaks. Try slowly pouring water into the hull and see where it comes out. Tipping the hull fore and aft and across the beam could also help to localise the leak(s).

2-pack epoxy, and other modern adhesives, can work wonders once you've found the areas of leakage.

Good hunting,

Dave

I have removed some earlier repair work that contained the point of entry of the water inside the boat and discovered some extensive damage and poor repair work in the past. I will upload a photograph tomorrow morning...

My feeling is that it will be important to stop the ingress from the outside and am considering using <https://www.rawlinspaints.com/home/metal-paints/metal-topcoats/3137-bradite-chlorinated-rubber.html> in red (below the waterline) in keeping with ships of this type and era. I'm hoping that as a liquid rubber paint it will seal the hull after a few coats.

Happy to hear all your thoughts!

Michael

Hi Dave,

So I have uploaded some more images of the removed previous repair to the inside of the hull and some details of the metal outer hull.

Looks to be made from Brass??

It also looks like she has been torpedo from the rear now i have removed the previous repair work...

Any comments gratefully received.

Michael

Ooo er Michael! Scrape all that muck out, rough up the area and fibreglass/epoxy resin I think to fix that. Externally, just red oxide paint should do, although some epoxy run into any external cracks may be needed, although the resin from the fibreglassing should penetrate those.

Bushy park 1hr 25 mins away according to google. Sunday Tuesday mornings, get there before 10 usually as it can get busy. Loo/catering on site. Entrance opp Hampton court palace lion gate. Car park 30 sec walk to pond.

Yes, Ashley's scraping method sounds like the way to go.

You may need to go easy in places though as you could go straight through ! I would do a couple of test patches first, then come back to us with some more photos. (It may just be brass-plated steel or similar...)

Make your own contribution to the Website

We welcome well written contributions from Website members on almost any aspect of Model Boating with a particular emphasis on practical hints, tips, experience and builds.

In order to maintain a consistent standard and format, all suggestions should first be sent to me by Personal Message for approval in principle. Only a very limited amount of time is available for editing contributions into a suitable format for placing on the website so it is important that the material is well presented, lucid and free from obvious spelling errors. I think it goes without saying that contributions should be illustrated by appropriate photos. I shall be happy to give advice on this.

The Member Contribution area offers space for short informative mini articles which would not normally find a place in Model Boats magazine. It is an opportunity for Website Members to freely share their  expertise and experience but I am afraid that virtue is its own reward as there is no budget to offer more material recompense!

I look forward to receiving your suggestions.
